Description

Searches the range [first, last) for a range of count elements each comparing equal to value (1,2). Searches the view for count elements each comparing equal to value (3,4). Searches the range [first, last) for a range of count elements for which the pred returns true for value in (5,6). Searches the view for a range of count elements for which the pred returns true for value in (7,8).

Parameters and Requirements

• exespace, first, last, view and count similar to for_each_n.

• label:

  • 1,5: The default string is “Kokkos::search_n_iterator_api_default”.

  • 3,7: The default string is “Kokkos::search_n_view_api_default”.

• pred - similar to equal
